Specification of Letters Patent.

Patented June 1 1, 1907.

Application filed September 12,1906. Serial No. 334,208.

To (LIZ wit/mt it mm, concern.-

Be it known that I, Enxns'r E. GAMoN, a citizen of the United States, residing at Long Island City, in the county of Queens and State of New York, have invented certain new and useful Improvements in Meters; and I do hereby declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same.

The object of my invention is to so construct a water meter as to make it possible to procure a uniform delivery from the meter as well as a uniform supply of water from the main feed pipe under varying heads of pressure, by providing a water meter which consists essentially of a main casing, a measuring main casing, communieating orifices in said casing and measuring chamber respectively and means for adjusting said orifices to correspond with the varyin pressures to which said meter may be subjected.

The improved fastening means whereby the sections of the caslng may be more readily connected together than has hitherto been the case in meters of this type, forms the subject matter of another application, Serial No. 334,234, filed September 12, 1906.

Other features of improvement will be disclosed in the following description, taken in connection with the accompanying drawings, in which Figure 1 is aside view of the meter with the parts assembled. Fig. 2 is a vertical section on line wa' of Fig. 3. Fig. 3 is a plan view of the lower section of the meter showing thedisk chamber in adjusted position. Fig. 4 is a plan View of the disk chamber removed from the meter casing. .Fig. 5 is a side elevation of the disk chamber, and Fig. 6 is a modified form of an adjustim means.

Similar letters of reference reier to like parts throughout the specification and drawm s.

The main casing or water chamber proper is formed of the upper section A and the lower section B connected together through the flanges A and B by means of the bolts C. Projecting from the lower section B at diametrical points are the inlet and discharge orifices 1) and E. The gear train or drives I are carried in a small case F secured to the upper or dome member A. The lower sec-- tion '13 is provided with the feet B cast mtegral with said section.

1 The lower section B is chambered as shown points or faces I), col'icentric with the vertical axis of the meter and tapering downwardly as illustrated in Figs. 2 and ,3. ends of these hearings terminate in the shoulders 1), upon which the disk chamber rests when in position.

The disk or measuring chamber G is made of the upper and lower sections g and g, secured together by means of the screws screwed into the flanges of the measuring chamber as illustrated. The bearing points g illustrated clearly in Fig. 5 are arranged upon the oircuml'erence oi' the chamber and designed to tit against the bearings b of the casing 13. These bearing points 9 taper from top to bottom so as to form a close lit when in position with the bearing faces I) of the section B.

Within the chamber is the usual 7 disk. ll carried by the spherical hearing I, which is supported by the top. and bottom bearings K and L, the adjustment being such that the spherical bearing 1 may move in any direction between said bearings K and l; in the usual manner, the upper hearing K having the opening A: for the passage of the driving pin-h hich .pin is usually connected up to the gear train leading to the indicator in any desired or preferred manner. The lateral interior surface oi the disk chamber is spherical as usual, the upper and lower portions being in the nature 01' frustums of cones so that the disk ll. when in operation always finds a bearing along some line of both the upper and lower cones of the chamber.

The chamber G is provided with a dia phragm M which extends from the outside of the sections of the chamber inwardly into contact with the spherical'bearing I being held in position by grooves formed in the upper and lower sections of the chamber as lllustrated in Fig. 5. It is understood that the disk 11 is divided as shown at [L2 with the diaphragm M lying in the slot formed by such division. In this manner, the disk is in Fig. 2, and provided with four bearing 0 o The lower wabbling permitted to operate or haveits wabbling motion in the usual manner without interference with the diaphragm.

The bearing 9 formed upon the outer surface of the chamber 9, is considerably broader than the bearing face 9" and extends circunit'erent-ially a distance sufficient to be capable of nearly shutting oil the dis'char e oritice E from the interior of the casing B: when in position. This bearing 9" also extends from the top to the bottom of the sections formingthe chamber G and has in its face a rectangular recess 9", the bottom of said recess being provided with the triangte lar orifice g" leading to the interior oi ,the disk chamber. At the right of the bearing g and 1 extending into the chamber are the two inlet orifices N, N covered by the strainers 11 said strainers being held in position by means of the clamps 1L'*"together with the projections n.

Any suitable means may be provided for tttl ]1li-llll{ the orifices to correspoml with the vat-yin pressures to which the said meter may be sub ected. In order, however, to

show an operative construction, 1 "have shown (see Fig. 5%), that one of the bearing faces 6 is provided with semi-circular, recesses f1 and that the upper tt'aceol the bearing surface g is provided with index arrows as illustruted, while the corresponding bearing g is provided with a small projection g, which when the chamber G isfinserted into the case in; B, rests in some one of the. recesses according to the desired adjustment of the dclivery orifice.- v

in the modification shown in Fig. 6, I (for ploy an external shaft pconnected to a pinion. p, said pinion being partially loeatedin a recess Formed in the metal of the casing l3 and projectingfar enough from the inner face oi" said case to-engage with a tooth rack suitably formed on the bearingsurfaee g of the measuring chamber case G. This structure would not-interfere with the structure shown in Fig. 3,t'nrasmuch as-the bearing surface I) of the main casing Band the etl'eetive bear ing surface g of the measuring chan'iber is not disturbed. Any suitable means \inay be connected to the shaft pout'side of the ease to indicate the position of the 'orilices and forv I ad usting the 801110) correspond w th the varying pressures to which said ineter may betsubjected.

should I find it desirable to regulate the intake openin instead of the delivery opening, it will only be necessary to change the position of the measuring chamber within the main casing in which case, the delivery orifice will become the inlet critic-e and the inlet orifice will become the delivery orifice.

In the position indicated in Fig 3, the index pointer 40 located adjacent the delivery orilicc. In such osition,a i'ueter of the type illustrated will deliver a certain in which case, the broa screwed honze into the threaded nutrm O ftDCl'lIl' this manner, the sections may bereadily connected together.

eases;

amount of water under 40 etinds normal be lifted out of the casing and turned until the projection 9 should register with the middle recess b aind the back into position bearing surface 9 would partially cover the discharge opening through the orifice E to such anextent as to reduce the quantity of water delivered. In like 1nanner, if the pressure should be increased to 100 pounds and it should be re qaired to have a delivery the same as in the first two cases, the chamberg will be adjusted so'as to bring the indicator t 0 adjacent to the delivery orifice with the projection g in the third recess b*. In this position, it will be seen that the bearing surface 9 more nearly closes thedischarge orifice E of the delivery orifice, thus reducing the outflow.

Water, in its passage through the meter, cones in at the intake orifice D and completely tills the interior portion of the casing or water chamber B, and thence through the l i miners 71 into the interior of the chamber G, where its passage causes the disk H to operate with its 'wabhling .motion and the water finds exit through the discharge 9 and the delivery oritice E;

' As a convenient means for connecting the- 0 consisting otthe series of nuts 0 connecte together by means of the base. plate or ring 0. The base ring o is made to conform to the flange B and may be secured thereto in small screws 0 'VVit-h the threaded nuts 0 registering with the apertures through the flange B, the bolts beinginsert-ed throu h the apertures otthe upper tlanqe A, 1118 be A and Tl e convenience of such a device, will be ap parent when it is; s ate'd that-ordinarily a meter is located in a it or trench considerably-below the groun level, where access to the same is onlvhad with ditlicnlty. When it is desired to inspect the ireter for prrpose of repair or otherwise, it. becomes necessary to remove the upper section A and in replac ing the snare, if independent nut-s were used,

nuts 0 o the I any convenient manner, as bv means of the considerable dilliculty would be met with in locating the said nuts in registry with the apertures through the flanges andin the narrow space, the independent nuts are liable to' ,slip from the hands of the operatorand become lost in the pit, whereas ay the structure above disclosed, the nuts are always held in position and in registry with the a ertures through the flanges, ready toinsert t 0 bolts ("t Another point in this connection should when screwing the bolts C home.

ssaaea be mentioned, and that is, that the base ring 0 being integrally connected to the nuts 0 serves to prevent the turning of the nuts 0 Should, however, in the continued use of the nut ring the threads in any particular not become stripped, the thinness of the conn .eting base ring 0 readily permits the nut to be broken away from the same andva new or independent nut to be substituted for the one so destroyed.

In meters of this type, the measuring chamber G is usually made of brass and where the bearings K and L are integral with the upper and lower heads of this chamber G, it is found that the spherical bearing .i has such abrasive eii'ect upon such bearings that they last but a short time. I have l O tnfl that by constructing the bearings K and ll of hard phosphor bronze, making them independent of the upper and lower heads of the chamber G shown, avoids this dillici lty and givesincreased length of life to the ireter. These bearings K and L are forced into place either by hydraulic pressure or by shrinking into position and are then turned or n' illed to fit the spherical bearing l. The sniall screws L may be utilized for holding the under bearing in position against accidental displacement if desired.

The disk II and the bearingi must in all cases, be made of hard rubber, and the bear ings K'and ll of phosphor bronze, in order that there shall be as little wear as possible to the parts.

Another feature of my invention resides in an improved thrust roller for the disk ii. In practice, unless some special arrangement is made, the twist or strain upon the shank of the roller is sufficient to break the same oil and thereby render the roller useless. By a special construction of the roller and its shank, I am enabled to so strengthen the same as to eil'ectually resist, not only the cree )ing tendency of the disk, but also, the liability of the shank of the roller to fracture. The roller 71 travels vertically in the curved slot If and is held in position upon the periphery of the disk ll by means of the long shank It" which is received into an aperture The rollerin the edge of the disk as shown. proper Ii is made of hard rubber and is rigidly mounted upon the shank Ir, the shank rotating with the roller.

The diaphragm M is secured in position in such. a. way as to preserve the integrity of the upper and lower walls of the disk chamber by curving-tho slots orgrooves mncar thcircnds,

so that they run substantially parallel with the outer faces of the upper. and lower walls without cutting through them, said slots extending through the outer face of the boaringsi'i'rlach g", as illustrated in Fig. 5, leaving solid metal at the upper and lower points of said bearing surface, and thereby adding ma- .iices, an angularly adjustable terial strength at these points. The contiguration of the slots is clearly shown in dotted lines in Fig. '3, where it will be noted that if said slots were continued in substantial radial lines, they would cut through both top and bottom. The curved extensions, however, as shown in said Fig. 2, leave the top and hot.- tom faces of the chamber sections unmu tilatcd and of their original strength.
